The rear cannot be aligned other than by loosening and retightening bolts and using the slack inherent in them. If you are having inside tire wear, it's likely the result of a toe-in or toe-out issue that may be the result of some damage or bending to some suspension part. The non-adjustable rear toe setting on a non-damaged 451 seems to be spot on and should not result in excessive inner tire wear.
Up front, the only standard adjustment is for toe, and the factory specification is terrible and causes problems like excessive understeer, wandering on uneven surfaces, and wind sensitivity.
The vast majority of modern alignment racks should be able to accommodate a 451.
